In Ms. Rickets’ mathclass, students made a “polygon path”that consists of regular polygons of 3, 4,5, and 6 sides joined together as shown

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

47 - 90 = 43

43 - 180 = x

x = 137

my guess would be b and d, but i didn’t actually get out the pen and paper. lol

the answer is 8/21

hope this
